The Boiler Room was an underground room below the Dance Club in Club Penguin Online. It was named after a boiler that served as a power source for the entire island. It also had a large filing cabinet, which hosted old issues of the Club Penguin Times. However as there was currently no newspaper in Club Penguin Online, the headlines were random and the newspapers were empty when clicked.
The Boiler Room could be accessed by climbing down from a fake speaker in the Dance Club, or from a door on the left side of the Underground Pool. In the missions it was also possible to see the back wall, which had a variety of tools and a fuse box.
